The code below compiles with javac but is rejected by eclipse Not yet sure what causes this, but initial analysis reveals that this has to do with the nested generic method invocation. Somewhere along the line, U is instantiated to be Integer instead of ? super Integer resulting in the error. public class Test { <T> A<? super T> getA(T t) { return null; } <U> A<U> getAU(A<U> u) { return null; } void foo() { A<? super Integer> a = getA(100); var var = getAU(getA(100)); var = a; // error here - cannot convert from A<capture of ? super Integer> to A <Integer> } } class A<Q> { A(Q e) { } A(A<Q> ae) { } }
